Pictaculous is an online image color extraction tool that lets you extract a palette of colors from any image. Just upload an image from your computer (up to 500 Kb) and hot on the “Get my palette”.

It gives you a set of colors extracted from the image along with a hexadecimal code of each color. Download the generated colors as an Adobe Swatch file (.aco) onto your computer or click to send results to your email.

There is also an iPhone version available, which lets you extract a palette of colors from any image captured with the iPhone’s camera.
